Morse , a painter and founder of the National Academy of Design, who, along with Alfred Vail a machinist and inventor, and the physicist Joseph Henry developed the electromagnetic telegraph and the code that assigns a set of dots and dashes or short and long pulses to each letter of the English alphabet.
The first working telegraph was produced in This made transmission possible over any distance. The first Morse Code message, "What hath God wrought? Today experienced operators copy received text without the need to write as they receive, and when transmitting, can easily converse at 20 to 30 words per minute.
Morse Code will always remain a viable means of providing highly reliable communications during difficult communications conditions. Morse Code can be transmitted using sound or light, as sometimes happens between ships at sea. It is used in emergencies to transmit distress signals when no other form of communication is available. Morse Code can be used to transmit messages in English and many other languages. This is the current international standard version. The Morse code is still widely used for amateur radio or ham radio applications.
It enables ham radio contacts to be made all over the world with ease, especially when using low powers or more modest antennas. While the Morse code is not generally widely used, it still has applications for ham radio, and the above Morse code chart or Morse code table is useful to identify the main symbols used.

For example in the case of 1'15'', the apostrophe signal. The signal. Sending whole numbers and fractions: A number that includes a fraction shall be transmitted with the fraction linked to the whole number by a single hyphen. A dash is equal to three dots The space between elements which form the same letter is equal to one dot. The space between two letters is equal to three dots The space between two words is equal to seven dots By keeping to these lengths the Morse code characters are much easier to read.
Summary The Morse code is still widely used for amateur radio or ham radio applications. The signals were sent by cutting up the continuous hum in the telephone into long and short periods in accordance with the Morse code by manipulating the key in the primary circuit. In this manner it was possible to hear a Morse code dash or dot in the telephone.
Hence according as the trains of oscillations are long or short so is the sound heard in the telephone, and these sounds can be arranged on the Morse code into alphabetic audible signals. Others were in Morse code or started with electronic music, similar to a Stylophone or musical doorbell.

A character code represented by dots and dashes short and long pulses , originally used to send messages by telegraph , later by flashes of light or by radio. A code developed by Samuel Morse used for transmitting messages in which letters of the alphabet and numbers are represented by various sequences of written dots and dashes, or short and long signals such as electric tones or voltages.
Morse code was used extensively in telegraphy. In a format that has been standardized for international use, it is still sometimes used for long distance radio communication.
The first widely accepted standard coding scheme for digital data communications. Morse code was invented by Samuel Morse sometime prior to for use with the electric telegraph. Friedrich Clemens Gerke invented the International Morse Code in out of necessity, as some of the spaces in letters created difficulty in radiotelegraphy. International Morse code was standardized by the International Telegraph Union ITU in and was widely used in radiotelegraphy through the early twentieth century.
